Ironwood Electronics
Ironwood Electronics has been the go-to source for advanced adapters, sockets, and modules. Our adapters convert package and pitch between devices, our modules offer complete fully tested assemblies for component replacement and upgrade, and our sockets allow for complete component and assembly testing - from new silicone characterization and validation, all the way thru burn-in and high volume automated testing – always with the highest performance and lowest possible footprint in the industry. Ironwood brings a combined knowledge of hundreds of years of engineering and manufacturing expertise, all under one roof in our state of the art 25,000 sq. foot facility just outside Minneapolis, Minnesota. Combined with our recent acquisition of the Grypper socket line, our continuous new product development demonstrates our on-going commitment to both our customers and the industry we serve.

Socket Accessories (SMT Options)
The SMT adapter consists of standard high temperature FR4 with plugged via technology, eutectic SN63PB37 solder balls or SAC lead free solder balls and threaded inserts for mounting the socket. The top side of adapter has SMT pads to receive socket interconnect and the bottom side has appropriate solder balls for corresponding pitch. This FR4 adapter with balls can be soldered to the SMT pads in the target board. Then socket can be mounted to the threaded insert on the FR4 adapter.

Open Top BGA Sockets
Ironwood has the most comprehensive collection of open top BGA and QFN sockets that can be used for qualification application, silicon FIB testing, system development, thermal characterization, burn-in application, etc. IC socket can be defined as an electromechanical device, which provides removable interface between IC package and system circuit board with minimal effect on signal integrity. Typical packages include BGA, LGA, QFN, QFP, WLCSP, etc. Open top allows access to the top side of IC. Below is an example BGA socket that uses low cost elastomer contact technology.

Grypper G35 / G40
*Package-size PCB footprint: Since the PCB footprint of Grypper is identical to the package, only one PCB design is required, enabling a seamless transition from test and validation through production and reducing overall cost of test*Low insertion force: Unique contact design reduces the insertion force required to insert and retain higher-ball-count packages safely and securely within the test socket*Oxide cutting wipe action: The contact design wipes the side of the solder ball during insertion, breaking through solder oxides ensuring a good electrical connection between contact and solder ball*Signal integrity: A short signal path achieves low inductance and low insertion loss, providing a nearly invisible electrical connection*Test socket has solder balls attached: The G40 contacts have solder balls reflowed onto the contacts to ensure reliable solder volume at the PCB to test socket solder interface.

Surface Mount Package Emulation
SMT Adapters
Ironwood’s SMT package emulation adapters are often called “surface mount feet” or “emulator bases”. These adapters provide access and interconnections to surface mount lands. Typically, the adapters are soldered to the target board in place of the IC device and provide a pluggable array of pins interface for sockets, probing adapters, package converters, and even board-to-board connections. These adapters are often utilized as a base for many of our probing adapter products. We constantly innovate to provide the most reliable, cost effective interfaces available. For example, many of our PLCC, QFP and SOIC emulation bases use our proprietary shaped solder techniques, replacing expensive, and often fragile, J-lead and Gull Wing leads. Shaped solder parts are easily fluxed and reflowed onto the target system. Our emulator bases can present either a male or female interface at 1.27mm or 1mm or 0.8mm pitch gold plated array pins for pluggable connection.

Silver Button Sockets
For BGA, QFN, or LGA applications, GTP contact technology provides >94 GHz signal speed and can additionally be used in high cycle life applications such as ATE. These sockets support pitches from 0.2 mm to 1.27 mm. Ironwood's GT sockets are ideal for prototyping and testing almost any BGA device application. These IC sockets provide excellent signal integrity yet remain cost effective. Innovative elastomer interconnect technology that delivers low signal loss (1dB at 94GHz) and supports BGA packages with pitches down to 0.2mm was utilized in these sockets. GT BGA sockets are mechanically mounted over a target system's BGA lands using mounting and alignment holes at proper locations (page 2 of the individual socket drawing shows recommended PCB layout information). These low-profile sockets are only 2.5 mm per side larger than actual IC packages (industry's smallest footprint).

Socket Accessories (Thru-Hole Options)
The male pin adapter consists of standard high temperature FR4 with pressed in terminal pins and threaded inserts for mounting the socket. The top side of adapter has gold plated pads to receive socket interconnect and the bottom side has 0.006″ to 0.018″ diameter pin tails. These pins can be soldered to the plated thru holes in the target board. Then socket can be mounted to the threaded insert.
